Sucker device

Abstract

The invention relates to a sucker device comprising an elastic base. The elastic base is at least used for being bent to form a negative pressure cavity under the action of set external force, and hermetically connected with a contact surface in a surrounding manner through a periphery portion of the negative pressure cavity to allow the sucker device to be sucked to the contact surface. The sucker device further comprises a force-separating structure connected with the elastic base. When external force applied to the elastic base is smaller than the set external force, at least parts of the force-separating structure expose out of the elastic base in a protruding manner; and when the elastic base is bent to form the negative pressure cavity under the action of the set external force, the force-separating structure is arranged in the negative pressure cavity, and the distance between the force-separating structure and the contact surface is larger than zero. The force-separating structure comprises at least one boss connected to the elastic base. The sucker device can be removed from the contact surface easily and conveniently with no need of reducing absorption force of a sucker, and accordingly, using too much external force or tools and the like are omitted. Besides, the sucker device is simple and convenient to operate and economic and efficient.

Description

technical field [0001] The present invention relates to a suction cup device that can be installed on a contact surface, in particular to a suction cup that can be easily and quickly removed from the contact surface. Background technique [0002] Suction cups with adsorption function have a wide range of applications in real life. For example, they are used as fasteners for hanging other items in family life, and can also be used as bearings for hanging or embedding wires. Therefore, enhancing the adsorption force of suction cups has always been an important The direction of key research in the field. [0003] When using the suction cup, it can be conveniently fixed on the contact surface. However, since the suction cup is mostly fixed on a smooth contact surface, and researchers have made great achievements in enhancing the suction force of the suction cup, this creates the problem of how to quickly and easily remove the suction cup from the contact surface. [0004] At p...

Problems solved by technology

However, there are many problems in the above method: first, the essence of adding ribs is to apply force at a certain point on the edge of the suction cup, and it still needs to be applied vigorously to the suction cup with strong adsorption force, which has not produced effective results; secondly, setting the space The disadvantage of the airbag is that if the air is squeezed too much in order to increase the adsorption force, the purpose of removal will not be achieved because there is no air to enter during the expansion of the airbag; The sealing of the suction cup is affected, which in turn affects the adsorption force. At the same time, the sealing edge may also increase the edge area due to the setting of too many moldings, which does not have great economic benefits.
